Prasanth Jayachandran commented on HIVE-12551:
----------------------------------------------
[~Feng Yuan] Can you provide a small reproducible test case for this issue?
This issues looks like PartitionDesc is not registered with kryo. I can fix
that but it will not guarantee that it will completely solve the issue. Adding
PartitionDesc alone won't be sufficient. It could show up some other issue
after this. To fix it completely, if you can provide a small data set and
queries that reproduces this issue, I will test the patch before updating the
JIRA.
